Misiones province covers < 1% of Argentina’s land area yet harbors > 50% of the country’s biodiversity, with a significant remnant of Atlantic Forest, a global biodiversity hotspot. Approximately 540,000 ha of this native forest is protected, with the remaining areas facing threats from ongoing land conversion, an expanding road network, and a growing rural population. A prior study incorporated noninvasive data on five carnivores into a multifaceted cost analysis to define the optimal location for a multispecies biological corridor, with the goal of enhancing landscape connectivity among protected areas. Subsequent analyses, with an updated framework, emphasized management strategies that balanced human–wildlife coexistence and habitat needs. Building on these efforts, our study applied ecological niche modeling to data located by conservation detection dogs, with genetics used to confirm species identity, and two land-use scenarios, to predict potential distributions of three game species—lowland tapir (Tapirus terrestris), white-lipped peccary (Tayassu pecari), and collared peccary (Pecari tajacu)—that are not only threatened by poaching, road mortality, and habitat loss but also serve as essential prey for carnivores. We assessed the suitability of unique and overlapping vegetation types, within and outside of protected areas, as well as within this multispecies corridor, identifying zones of high conservation concern that underscore the need for integrated planning of predators and prey. These results highlight that ensuring the long-term viability of wildlife across the heterogeneous land-use matrices of Misiones requires going beyond protected areas to promote functional connectivity, restore degraded habitats, and balance human–wildlife needs.

This narrative literature review aims to explore the risk and protective factors influencing the mental well-being of white-collar workers in the post-pandemic era. It investigates how factors vary across different phases, including pre-pandemic traditional work models, work-from-home or hybrid models during the pandemic, and the recovery phase of returning to the office in the post-pandemic era. This review highlights the diverse nature of related factors, examining constructs including stress, depression, burnout, thriving, work engagement, workaholism, motivation, workplace civility, and resilience. The Job Demands-Resources model, a recognized theoretical tool for analyzing and understanding the interactions between psychological constructs and their effects on employee well-being and turnover intention, is proposed as a useful framework to consider the relationships between the factors. By synthesizing existing research findings, this review contributes to our understanding of the complex interplay between work-related factors and employee well-being in the evolving landscape of the post-pandemic world. Understanding these dynamics is crucial for developing effective strategies to support white-collar workers’ mental well-being and productivity in the post-pandemic era. Full article

Ganoderic acid (GA) is a key bioactive component with pharmacological properties that is found in Ganoderma lingzhi, a renowned medicinal mushroom. Currently, the regulatory mechanisms underlying GA biosynthesis in G. lingzhi remain to be further elucidated. In this study, blue light induction was found to significantly enhance the GA content in G. lingzhi. To explore the regulatory mechanism of GA biosynthesis in response to blue light, the blue light receptor WC-2 was identified, and its regulatory role was characterized. The deletion of wc-2 resulted in a significant reduction in both GA content and the accumulation of intermediates compared to the wild-type control strain, largely due to the strong downregulation of key GA biosynthetic genes. Additionally, decreased asexual spore production and reduced expression of sporulation-specific genes were observed with the deletion of wc-2. The overexpression of wc-2 led to greatly enhanced GA accumulation. Under blue light induction, the maximum contents of GA-Mk, GA-T, GA-S, and GA-Me were 2.27-, 2.51-, 2.49-, and 2.08-fold higher, respectively, compared to the control kept in darkness. These results demonstrate that the blue light receptor WC-2 functions as a positive regulator of GA biosynthesis in G. lingzhi, influencing the expression of genes involved in GA biosynthesis and asexual spore production, thereby advancing our understanding of the intricate regulatory network of GA biosynthesis.

Fungi, from saprophytes to pathogens, face predictable daily fluctuations in light, temperature, humidity, and nutrient availability. To cope, they have evolved an internal circadian clock that confers a major adaptive advantage. This review critically synthesizes current knowledge on the molecular architecture and physiological relevance of fungal circadian systems, moving beyond the canonical Neurospora crassa model to explore the broader phylogenetic diversity of timekeeping mechanisms. We examine the core transcription-translation feedback loop (TTFL) centered on the FREQUENCY/WHITE COLLAR (FRQ/WCC) system and contrast it with divergent and non-canonical oscillators, including the metabolic rhythms of yeasts and the universally conserved peroxiredoxin (PRX) oxidation cycles. A central theme is the clock’s role in gating cellular defenses against oxidative, osmotic, and nutritional stress, enabling fungi to anticipate and withstand environmental insults through proactive regulation. We provide a detailed analysis of chrono-pathogenesis, where the circadian control of virulence factors aligns fungal attacks with windows of host vulnerability, with a focus on experimental evidence from pathogens like Botrytis cinerea, Fusarium oxysporum, and Magnaporthe oryzae. The review explores the downstream pathways—including transcriptional cascades, post-translational modifications, and epigenetic regulation—that translate temporal signals into physiological outputs such as developmental rhythms in conidiation and hyphal branching. Finally, we highlight critical knowledge gaps, particularly in understudied phyla like Basidiomycota, and discuss future research directions. This includes the exploration of novel clock architectures and the emerging, though speculative, hypothesis of “chrono-therapeutics”—interventions designed to disrupt fungal clocks—as a forward-looking concept for managing fungal infections.

The decline in mental health among workers in Japan has become a serious concern. Autism spectrum disorder (ASD) traits are increasingly recognized as a potential risk factor for mental health issues, yet few individuals receive a formal ASD diagnosis. This study aims to examine whether undiagnosed but working individuals with strong ASD characteristics differ in factors related to presenteeism (low productivity) compared to their counterparts with fewer ASD traits. In particular, we investigated the impact of social camouflaging—the behavioral adaptation used to mask ASD traits—especially on workers with strong ASD characteristics. An online survey was conducted among white-collar workers aged 20 to 60. The survey included items collecting demographic information (gender, age, marital status, highest level of education completed, employment status, job title, length of employment, and working hours) and included the Japanese versions of four validated instruments to measure aspects of autism traits, social camouflaging, work functioning, and occupational stress. Of the 543 respondents, 139 (25.6%) exhibited strong ASD characteristics. These individuals reported lower productivity than their counterparts. While social camouflaging was observed across all ASD trait levels, it was specifically linked to poorer mental health and reduced productivity among workers with strong ASD characteristics. To support workplace well-being and productivity, it is crucial to increase awareness and understanding of ASD traits in professional settings and create an environment that accommodates diverse work styles.

Background/Objectives: The structural integrity and strength of the transgingival soft tissue seal around dental implant surfaces remain critical challenges. Therefore, animal models should include all three implant/tissue interfaces: bone, connective tissue, and epithelium. Thus, we sought to explore the rabbit mandibular diastema as a site for candidate intra-oral implant placement. Methods: Ninety-six custom mini-implants (with one of four different surfaces: machined, acid-etched, and with or without a nanotube coating) made from titanium 6/4 alloy were placed in the mandibular diastemas of twenty-four 16-week-old New Zealand white rabbits, with the implant collar above the alveolar crest. After 7, 21, and 42 days, the bony and connective tissue/implant interfaces were examined by light and scanning electron microscopy (SEM). Results: Of ninety-six implants, eight implants were found exposed to the oral cavity, with no evidence of soft tissue inflammation, suggesting that transmucosal implant placement would have been feasible. No significant differences were observed in collagen fiber orientation and fibrous tissue thickness by polarized light microscopy. However, SEM images showed that at all three time points, topographically complex nanotube surfaces had a profound effect on soft tissue peri-implant deposition, although functionally oriented collagen fibers were not identified attached to the implant surface. These surfaces also showed reparative peri-implant bone in the collar region. An intramembranous form of de novo bone formation was observed, together with tartrate-resistant acid-phosphatase-positive osteoclasts and multinucleate giant cells in the peri-implant endosseous compartment. Conclusions: Our results demonstrate that the rabbit mandibular diastema provides an intra-oral method of implant placement without the necessity of an extra-oral approach, tooth extractions, or bone augmentation procedures. Furthermore, given that three implant tissue interfaces can potentially be studied (bone, connective tissue, and epithelium) this model provides advantages over more traditional implant placement sites in the appendicular skeleton.

This study aims to determine the effects of the variables within the UTAUT 2 model on the intention to use a Fully Electric Car. In this context, data were collected through survey forms from 401 white-collar workers who are considered to have a higher economic status. Initially, validity and reliability analyses were conducted on the scales used in the Smart PLS program, and subsequently, the hypotheses were interpreted using the results obtained from structural equation modeling. In this study, it was found that effort expectancy, social influence, perceived ease of use, hedonic motivation, and habit had a positive and significant impact on the intention to use electric vehicles. Performance expectancy has a negative and significant effect on the intention to use electric cars, while price has no significant effect. It was determined that the intention to use electric vehicles was found to mediate the relationship between perceived ease of use and actual usage behavior. This research can offer significant contributions to literature, particularly by examining the influence of habit on behavioral intention and the effect of hedonic motivation on electric vehicle usage intention. By testing the UTAUT 2 model in the context of electric vehicle acceptance, this study supports the universality and applicability of the model to various technologies. Emphasizing the role of variables such as hedonic motivation and habit in electric vehicle acceptance adds a new dimension to the UTAUT 2 model. Thus, it makes an important contribution to technology acceptance research. Full article

The COVID-19 pandemic has fundamentally transformed workplace dynamics worldwide. Within this context, emerging patterns in job demand and job resources necessitate a thorough examination of how these workplace changes affect work–family interference and employee well-being across diverse occupational categories. The current study investigates the differential impact of job characteristics on job satisfaction and work stress during the COVID-19 pandemic, comparing blue-collar and white-collar occupations in China. Drawing from the Chinese General Social Survey (CGSS) database, we conducted a cross-sectional analysis using data from two time periods, 2015 and 2021, encompassing 10,968 and 8148 valid samples, respectively. Through bootstrapping analysis, we tested the indirect effects of job characteristics on employee well-being, mediated by work–family interference. The results reveal distinct patterns across occupational categories. Blue-collar workers demonstrated increased susceptibility to work-related stress, primarily due to the compounding effects of dual workload demands that intensified their work–family interference. Conversely, white-collar employees maintained a positive relationship between job autonomy and job satisfaction, despite the negative mediating influence of work–family interference. Full article

Conservation strategies that use sustainable use of natural resources through green-labelled markets generally do not recognize the legal sale of wild meat as appropriate due to potential overexploitation and zoonotic disease risks. Wildlife hunting is important to the livelihoods of rural communities living in tropical forests for protein and income. Wildlife management plans in the Peruvian Amazon permit hunting of wild meat species for subsistence and sale at sustainable levels, that include peccaries, deer, and large rodents. These species have fast reproduction making them less vulnerable to overhunting than other species. This study assessed the sustainability of a wildlife management plan. Populations of species were estimated using camera traps and distance transect surveys, and sustainability analysis used hunting pressure from community hunting registers. Interviews were conducted to understand hunters, perceptions of the management plan. Long-term time-series showed increases in collared peccary (3.0 individual/km² to 5.41 individual/km²) and white-lipped peccary (3.50 individual/km² to 7.00 individual/km²) populations and short-term time series showed a decline in paca populations from 8.5 individual/km² to 3.01 individual/km². The unified harvest analysis showed permitted species populations were greater than 60% of their carrying capacities and hunted at less than 40% of their production, which shows sustainable hunting. The wildlife management plan achieved its general objective of sustainable hunting and improving livelihoods. The broader question is whether sustainable wildlife use plans that allow Amazonian communities to sell limited amounts of wild meat can be a way to change illegal wild meat trade to a legal, green labelled trade with added value.

Background: In Poland, a national hepatitis B (HBV) immunization program was introduced for neonates in 1996, and between 2000 and 2011, those born from 1986 to 1995 were vaccinated. Little is known about vaccination rates among adults born before 1986. This study aimed to determine the frequency of anti-HBs seropositivity rates related to vaccination and past HBV infection in older Poles. Methods: The HBV serological status was analyzed in 5781 (96.6%) of the PolSenior2 population-based cohort (60+) by assessing serum seropositivity for HBs antigen, anti-HBs, and anti-HBc antibodies. The survey was performed in 2018–2019 and included medical and socio-economic questionnaires, anthropometric measurements, and comprehensive geriatric assessment. Results: Serological status implying past hepatitis B and serological profile consistent with anti-HBV vaccination corresponded to 15.2% (95% CI: 13.4–17.0) and 25.2% (95% CI: 23.4–27.0) prevalences, respectively. Female gender, living in a town or city, having better education, and suffering from coronary artery disease, or depression independently increased the rate of past hepatitis B. On the other hand, being ‘white collar’ and self-reliant, having the ability to use the Internet, and past surgical procedures in the last 5-year period were factors associated with a higher vaccination rate. Conclusions: More than 15% of older adults in Poland present serological profiles suggesting past hepatitis B, and one-fourth anti-HBV vaccination. Being functionally independent, ‘white collar’, using the Internet, and having past surgical procedures are factors associated with a higher chance of being vaccinated. Nevertheless, a large group of older adults should be prophylactically vaccinated due to increased exposure to medical procedures. Full article

Current work environments, driven by globalization, demographic changes, and digitalization, demand substantial adaptation, which leads to decreased employee well-being. While occupational psychology research has identified supportive mechanisms, it often lacks a deepened understanding of how interventions function. This study aims to analyze the impacts of VUCA contexts and leadership behavior on job crafting, focusing on white-collar workers. Our objective is to identify workplace configurations that safeguard employee health in dynamic settings. Utilizing the JD-R model augmented by job crafting as a theoretical framework, we conducted qualitative comparative case studies using the GABEK^® methodology to analyze and systematize data. This approach captures complex organizational interrelationships through sentence analysis, transforming subjective meanings into a comprehensive network and providing deeper insights into organizational dynamics. Research findings reveal that evolving work demands, notably from digital transformations, impact knowledge management, communication, and employee well-being. IT discrepancies and communication deficits intensify work complexity, underscoring the need for enhanced management frameworks. Proactive and adaptive leadership, along with job crafting, is crucial for protecting health and enhancing performance in fast-paced digital environments. These strategies promote structured decision-making and efficient knowledge management, fostering a resource-oriented culture that enhances employee well-being and overall effectiveness.

This study examined the relationships between job-related factors and overall physical activity (PA), including its subdivisions: leisure-time PA, transportation PA, and work-related PA. Additionally, this study investigated the associations between exercise intentions and different types of PA. A cross-sectional design was employed, utilizing a questionnaire to collect data on participants’ demographics, job-related characteristics, exercise intentions, and levels of PA. A total of 400 full-time workers voluntarily participated in this study. The findings identified women, white-collar workers, those with longer working hours, and individuals with low exercise intentions as high-risk groups for insufficient overall PA in multiple linear regression analysis. After controlling for covariates, occupation was found to be associated with both overall PA (β = 0.146) and work-related PA (β = 0.236). Shift workers exhibited higher levels of work-related PA (β = 0.234). Furthermore, exercise intentions showed associations with overall PA (β = 0.243), leisure-time PA (β = 0.523), and transportation PA (β = 0.176) but did not demonstrate a significant relationship with work-related PA. This study highlights the importance of implementing comprehensive approaches in workplace health promotion programs aimed at enhancing various types of PA. Strategies should focus on improving exercise intentions to boost leisure-time and transportation PA, while work-related PA requires tailored interventions based on job-specific factors.

To enhance and advance both human and planetary health, it is imperative to transition towards more sustainable nutrition approaches. This study aimed to assess the correlation between the levels of sustainability and sustainable nutrition knowledge, attitudes towards sustainable nutrition, and adherence to the Mediterranean diet (MD) among blue- and white-collar employees. This study included 210 adults, half of whom were white-collar employees, with the other half being blue-collar employees. Sociodemographic data were collected, and anthropometric measurements were performed. The Questionnaire on Food Sustainability Knowledge and Attitudes to Sustainable Eating and the Mediterranean Diet Adherence Scale (MEDAS) were also included in the applied survey. Dietary intake was assessed using 24 h dietary records. The mean age was 41.9 ± 10.87 years. Of the participants, 56.2% were classified as being overweight or obese. The level of knowledge on the concept of “food sustainability” among all participants was 30.5%. The mean MEDAS score of all the participants was 5.4 ± 1.90, and 74.8% of all the participants did not follow the MD. Positive correlations were found between the MEDAS score and the Sustainable Diet Definition score (r = 0.174) (p ˂ 0.05) and Sustainable Eating Attitude score (r = 0.312) (p ˂ 0.001). Negative correlations were found between the MEDAS score and body weight (r = −0.320; p ˂ 0.001), BMI (r = −0.249; p ˂ 0.001), waist circumference (r = −0.278; p ˂ 0.001), and PBF (r = −0.177; p ˂ 0.05). We found that, as the level of sustainable nutrition knowledge increased, sustainable nutrition behaviors improved, and as adherence to the MD increased, the incidence of obesity decreased.

Background: Neck pain (NP) is a prevalent musculoskeletal disorder, especially among individuals with sedentary occupations. The interplay between cervical and thoracic spine mobility is hypothesized to contribute significantly to NP severity, yet this relationship requires further exploration. Methods: This cross-sectional study involved 179 young white-collar workers with NP lasting for at least six weeks. Participants were stratified into mild (n = 78) and moderate (n = 101) pain groups based on their scores on the Northwick Park Neck Pain Questionnaire (NPQ). Cervical and thoracic range of motion (ROM) in the sagittal plane was measured using inclinometers. NP severity was further assessed using the NPQ and the Neck Disability Index (NDI). Correlation, regression, and mediation analyses were conducted to investigate the relationship between cervical and thoracic ROM and NP severity. Results: Thoracic ROM was higher in the mild pain group (median: 47.35, IQR: 10.13) than in the moderate pain group (median: 42.10, IQR: 13.60; p < 0.001). The NDI had a negative correlation with thoracic ROM (r = −0.65; p < 0.05) and a positive correlation with cervical ROM (r = 0.84; p < 0.01). Additionally, thoracic ROM mediated the effect of cervical ROM on NP, particularly influencing NDI scores (p < 0.01). Conclusions: This study found a significant association between reduced thoracic ROM and increased NP severity, highlighting the role of thoracic spine mobility in NP among young white-collar workers. Targeted interventions for thoracic dysfunction may reduce compensatory cervical strain and improve NP management, suggesting that thoracic spine assessments should be integrated into routine clinical evaluations.

During the present study, DNA sequence and morphological data were used to delineate species boundaries in the velvet worm, Peripatopsis sedgwicki species complex. The combined mitochondrial cytochrome c oxidase subunit one (COI) and the nuclear 18S rRNA loci were phylogenetically analyzed using Bayesian inference and maximum likelihood platforms that both demonstrated the presence of four, statistically well-supported clades (A–D). In addition, five species delimitation methods (ASAP, bPTP, bGMYC, STACEY and iBPP) were used on the combined DNA sequence data to identify possible novel lineages. All five species delimitation methods supported the distinction of the Fort Fordyce Nature Reserve specimens in the Eastern Cape province, however, in the main P. sedgwicki s.l. species complex, the species delimitation methods revealed a variable number of novel operational taxonomic units. Gross morphological characters were of limited utility, with only the leg pair number in the Fort Fordyce Nature Reserve specimens and the white head-collar of the Van Stadens Wildflower Nature Reserve specimens being diagnostic. The RADseq results from the earlier study of P. sedgwicki s.l. provided highly congruent results with the four clades observed in the present study. The distribution of P. sedgwicki s.s. (clade B) is restricted to the western portions of its distribution in the Afrotemperate forested regions of the Western Cape Province, South Africa. Three novel species, P. collarium sp. nov., (clade C) P. margaritarius sp. nov., (clade A) and P. orientalis sp. nov., (clade D) are described, of which the first two species are narrow range endemics. The present study, along with several recent systematic studies of velvet worms affirms the importance of fine-scale sampling to detect and document the alpha taxonomic diversity of Onychophora.
